search所有表，所有列为一个特定的值SQL Server

我有一个具体的价值，让我们说string“评论”。 我需要在数据库中查找所有这些实例，因为我需要对格式进行更新以将其更改为（*）注释。 我该怎么做？ 请帮忙！ 数据库是SQL Server 2000格式。

我刚刚更新了我的博客文章，以更正您在使用Jeff的脚本中的错误，您可以在此处看到更新的脚本： searchSQL Server数据库中的所有字段

根据要求，这是脚本，如果你想要它，但我build议阅读博客文章，因为我不时更新它

我在这里发布了一个： FullParam SQL Blog

下面的查询工作，但很慢…从vyaskn.tripod.com复制

 Declare @SearchStr nvarchar(100) SET @SearchStr='Search String' BEGIN CREATE TABLE #Results (ColumnName nvarchar(370), ColumnValue nvarchar(3630)) SET NOCOUNT ON DECLARE @TableName nvarchar(256), @ColumnName nvarchar(128), @SearchStr2 nvarchar(110) SET @TableName = '' SET @SearchStr2 = QUOTENAME('%' + @SearchStr + '%','''') WHILE @TableName IS NOT NULL BEGIN SET @ColumnName = '' SET @TableName = ( SELECT MIN(QUOTENAME(TABLE_SCHEMA) + '.' + QUOTENAME(TABLE_NAME)) FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_TYPE = 'BASE TABLE' AND QUOTENAME(TABLE_SCHEMA) + '.' + QUOTENAME(TABLE_NAME) > @TableName AND OBJECTPROPERTY( OBJECT_ID(QUOTENAME(TABLE_SCHEMA) + '.' + QUOTENAME(TABLE_NAME)), 'IsMSShipped') = 0) WHILE (@TableName IS NOT NULL) AND (@ColumnName IS NOT NULL) BEGIN SET @ColumnName = ( SELECT MIN(QUOTENAME(COLUMN_NAME)) FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_SCHEMA = PARSENAME(@TableName, 2) AND TABLE_NAME = PARSENAME(@TableName, 1) AND DATA_TYPE IN ('char', 'varchar', 'nchar', 'nvarchar') AND QUOTENAME(COLUMN_NAME) > @ColumnName) IF @ColumnName IS NOT NULL BEGIN INSERT INTO #Results EXEC ( 'SELECT ''' + @TableName + '.' + @ColumnName + ''', LEFT(' + @ColumnName + ', 3630) FROM ' + @TableName + ' (NOLOCK) ' + ' WHERE ' + @ColumnName + ' LIKE ' + @SearchStr2 ) END END END SELECT ColumnName, ColumnValue FROM #Results END

您可以查询sys.tables数据库视图以获取表的名称，然后使用此查询构build自己的另一个查询来执行更新。 例如：

 select 'select * from '+name from sys.tables 

会给你一个脚本，它将对系统目录中的所有表运行一个select *，你可以改变select子句中的string来进行更新，只要你知道列表中的列名是相同的希望更新，所以你的脚本看起来像这样：

 select 'update '+name+' set comments = ''(*)''+comments where comments like ''%comment to be updated%'' ' from sys.tables 

您也可以对表查询进行谓词只包含具有特定格式名称的表，或者位于要为其创build更新脚本的子集中。
